IRIVIN B. CI-IRISSINGER, OF CHICAGO, ILLINOIS, ASSIGNOR TO CLINTON S.WEEKS AND M. F. OHRISSINGER, OF SAME PLACE.

DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 577,913, dated March 2,1897.

Application filed May 20, 1896.

T0 aZZ whom it may concern.-

Be it known that I, IRWIN B. OHRIssINGER, a citizen of the UnitedStates, residing at Ohicago, Cook county, Illinois, have inventedcertain new and useful Improvements in Dumping-WVagons, of which thefollowing is a specification.

The object of my invention is to make a simple, inexpensive, butefficient and serviceable dumping-wagon; and my invention consists inthe features and details of construction hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a longitudinal section of mydum ping-wagon, showing the wagon-body in a tilted position; Fig. 2, asectional elevation on line 2 of Fig. 1; Fig. 3, a sectionalplan of thewagon-frame with the wagon-body removed; Fig. 4, a transverse section online 4 of Fig. 3, and Fig. 5 a detail view of the ratchet-wheels at oneside of the wagon-frame. I

In making my dumping-wagon I first construct a wagon-frame A, connectedto suitable running-gear. This frame is rectangular, and, as illustratedmore particularly in Fig. 4.- of the drawings, it is provided withinterior recesses or channels a, which run longitudinally along thesides of the wagonframe. The upper flange or projecting portion a iscontinuous except at a predetermined point, where openings A, oppositelydisposed, are provided for a purpose hereinafter to be designated. Ifpreferred, a thin strip of metal may be secured to the bottom of therecess in order to form a smooth and substantial track for wheels orrollers to travel upon.

The wagon-body proper consists, essentially, of a rectangular box or bedB of a size to fit upon the wagon-frame. Upon the bottom of the box andat the proper points thereupon I arrange blocks B and O. The lower outerends of the blocks are provided with rollers or equivalent devices Z)and a, re spectively, which rollers are adapted to travel within therecess a when the wagon-bed is moved.

As shown in Fig. 1, the openings A and the block 13 are so disposed withrelation to each other that when the rear rollers a have reached therear end of the recess the wagon- Serial No. 592,246. (No model.)

' body will be free to tilt, inasmuch as the rollers 12, which had beenconfined within the recess, are in this position allowed to passupwardly through the openings A.

Two Winding-shafts D E are suitably mounted in any convenient place uponthe wagonframe, but preferably as shown in the drawings, and the end ofeach is constructed to receive a crank 01. Near the end of each shaft isa ratchet-wheel and dog or pawl F f of the usual and well-knownconstruction.

Connected to the block B is a rope or small cable G, which passes to thefront of the wagon around a pulley G, and thence around thewinding-shaft D. This pulley may be arranged as shown or located in anyother desirable place so long as the desired purpose is accomplished.

Two similar ropes or small cables H H are secured to the rear block 0,passing around pulleys H, secured to the end of the wagonframe, andthence around the windingshaft E. I prefer to employ a set of cablesupon this shaft in order to secure a straight pull on the wagon-box andprevent any liability of wedging or sticking, although one cable mightanswer the purpose. Furthermore, the position of these pulleys may bealtered, if desired.

Upon the top face of the wagon-frame I arrange any number of suitablerollers J, preferably as shown in the drawings. When the bed is beingmoved upon the frame, it bears upon the rollers and travels easily.

My dumping-wagon,being constructed as hereinbefore set forth, operatesas follows: The wagon body or box being in normal position on the frame,the winding-shaft E is rotated to wind up the cable II and thus draw theblock 0 and the box backward upon the wagon-frame, the rollers 19 atraveling in the recess a. It is understood that when the shaft E isrotated the ratchet device on the shaft D is released in order to allowthe cable G to unwind.

When the wagon-bed is in position to tilt, the openings A will besituated directly above the rollers 12, which will be free to pass outtherethrough. The bed will then assume the position shown in Fig. 1.. Inthis position it is noticed that the rollers c or pivotal ICO points ofthe bed are directly over the rear aXle of the wagon, which arrangementwill be found the most desirable and practical in operation.

When the bed is restored to its normal position, the operation of thewinding-shafts is reversed, that is, the shaft D is rotated to wind upcable G and shaft E is allowed to unwind cable H. Upon the first windingof cable G the bed is drawn from a tilted to a horizontal position, andthe position of the rollers Z) coinciding with the openings A the formerwill enter in the recess and by the continued winding of the shaft theywill travel forward therein, when the wagon-bed will assume its normalposition with respect to the wagon-frame. At this time the shaft D hasbeen unwinding and the rollers 0 have been traveling forward in therecesses. hen the bed is being moved either forward or backward, thebottom thereof rests 011 the rollers J on the wagon-frame, whereby theeasy movement thereof is assured.

It is obvious that my invention may be applied to a car or other vehiclewithout sufficient change to depart from the spirit and scope of myinvention, and, furthermore, that, if desired, the bed may be made todump either front or back by arranging the openings A at the center andso constructing and positioning the blocks B C that when either oneisdrawn to the limit of the recesses or channels the other will be free topass out through the opening, thereby permitting of a front or end dumpwithout material alteration of the parts.

Although I have described more or less precise forms and details ofconstruction, I do not intend to be understood as limiting myselfthereto, as I contemplate changes in the form, the proportion of parts,and the substitution of equivalents,as circumstances may suggest orrender expedient and without departing from the spirit of my invention.

I claim 1. In a dumping-wagon, the combination of a wagon-frame providedwith internal longitudinal recesses or channels extending substantiallyfrom end to end of the frame and having one pair of openings into thetop of the recesses, and a wagon bed or body having two pairs oflaterally-projecting pins eX- tending into the recesses and supportingthe bed upon the frame, one pair of pins being adapted to pass outwardlythrough the openings in the top of the recesses when the bed is tiltedupon the other pair of pins as a pivot.

2. In a dumping-wagon, the combination of a wagon-frame provided withinternal longitudinall y-eXtendin g recesses or channels havingcorresponding side openings cut in the top flange of the recesses, awagon body or bed, depending blocks upon the bed provided with sideprojecting portions engaged by the recesses and adapted to move thereinand means for moving the bed upon the frame whereby as the bed is movedto tilting position the projecting portions of one of the blocks will befree to pass through the openings in the recesses to allow the bed totilt.

In a d um ping-wagon, the combination of a wagon-frame provided withinternal longitudinally-extending recesses or channels having twocorresponding side openings in the top flange of the recesses, a wagonbody or bed, two depending blocks upon the bed, laterally-projectingrollers mounted upon the ends of each block and adapted to travel withinthe recesses, cables secured to the bed and means for operating thecables to move the bed upon the frame, whereby, as the bed is moved to atilting position the rollers on one of the blocks will correspond inposition with the openings in the recesses and be released from therecesses and be permitted to tilt.

4. In a dumping-wagon the combination with the running-gear, of awagon-frame provided with internal recesses or channels having twocorresponding side openings in the top flange of the recesses, the rearend of the recesses terminating at a point above the rear axle of thewagon, a wagon body or bed, two dependingblocks upon the bed providedwith laterally-extending portions engaged by the recesses and adapted tomove therein, and means for moving the bed upon the frame, the blocksbeing so spaced upon the bed with respect to the two said openings thatwhen the rear block has reached its rearward limit of movement above therear axle, the position of the projecting portions of the front blockwill correspond with the openings in the recesses, whereby the wagon-bedis free to tilt.

5. The combination of a wagon-fraine provided with internal recesseshaving corresponding side openings in their top, a wagonbed, dependingblocks thereupon provided with side projecting portions engaged by therecesses and adapted to travel therein and two winding-shafts journaledin the wagonframe and cables connected therewith and with the front andrear portions of the wagonbody.

6. The combination of a wagon-frame with recesses a having openings A inthe top thereof, a wagon-bed, blocks B 0 having rollers?) 0respectively, a winding-shaft D, cable II connected thereto and to block0, windingshaft E, cable G connected to shaft E and to block B andratchet device F f at the end of the shaft.
